Detailed Description

When using a camera, there are several times when some form of feedback to the user is given - for example, when an image is taken, or when recording is started. You can enable or disable some of this feedback, or adjust what sound might be played for these actions.

In some cases it may be undesirable to play a sound effect - for example, when initiating video recording the sound itself may be recorded.

Note: In some countries or regions, feedback sounds or other indications (e.g. a red light) are mandatory during camera operation. In these cases, you can check isEventFeedbackLocked to check if that type of feedback can be modified. Any attempts to change a locked feedback type will be ignored.

Member Type Documentation

enum QCameraFeedbackControl::EventType

This enumeration describes certain events that occur during camera usage. You can associate some form of feedback to be given when the event occurs, or check whether feedback for this event is enabled or locked so that changes cannot be made.

When the given event occurs, the sound effect referenced by filePath will be played instead of the default sound.

If this feedback type is locked, or if the supplied path is inaccessible, this function will return false. In addition, some forms of feedback may be non-auditory (e.g. a red light, or a vibration), and false may be returned in this case.

The file referenced should be linear PCM (WAV format).

Note: In the case that a valid file path to an unsupported file is given, this function will return true but the feedback will use the original setting.
